Question

Why do cooking vessels usually have copper bottoms?

• A. Copper is cheap.
• B. Copper is a good conductor of heat
• C. Copper has low melting point.
• D. Copper is an insulator of heat.

Answer 1

The correct option is B Copper is a good conductor of heat

Cooking vessels usually have copper bottoms because copper is a good conductor of heat. Hence, it allows heat to pass through it easily and helps in getting the food cooked.
The whole vessel cannot be made up of copper as it will react with the food. Hence, only the bottom of the vessel is coated with copper which is the part in contact with heat.
